Abstract

An ultra-hard semiconductive polycrystalline diamond (PCD) material formed with semiconductive diamond particles doped with Li, Be or Al and/or insulative diamond particles having semiconductive surfaces is provided. The ultra-hard PCD material may be formed using a layer of insulative diamond grit feedstock that includes additives therein, then sintering to convert a plurality of the diamond crystals to include a semiconductive surface. In another method, the ultra-hard PCD material is formed by sintering semiconductive diamond grit feedstock consisting of diamond crystals doped with Li, Al or Be. The ultra-hard semiconductive PCD cutting layer exhibits increased cuttability, especially in EDM and EDG cutting operations.
